The “advance of a brother toward a sister”? Good grief. The judge is not only nuts, he’s a male-dominant sexist. Nobody else could construct that phrase.
If any modern society ever accepts incest, it will be if and when some large number of sisters want to advance toward some large number of their brothers. Don’t hold your breath for this.

And this is relevant to a rape case how? Perhaps fortunately, law and custom deal with incest on the margin, the “westermarck effect” precludes it in anything like a functional family,

“And this is relevant to a rape case how?”
It may have been statutory rape. No doubt those laws will be revised to put ages lower and lower, if the age limit of consent is not thrown out altogether.

The statements might make us uncomfortable but they are logical and using the prevailing morality, morally acceptable. People who keep saying culture is changing all the time cannot complain when these things happen.
